Simulation of Grain Growth under the Effect of Stress

Abstract

Abstract.are preferentially eliminated, thus leading to interface texture development and a higher pop-ulation of low energy grain boundaries. However, when stress is introduced as an additionaldriving force, the dynamics of grain growth change. To model these effects, a three dimensionalanisotropic multi-level set model was modified in order to account for the effect of stress field ongrain growth. For this mesoscale study, grain boundaries were treated as dislocation structuresand their associated net Burgers vectors were calculated using the misorientation informationand boundary inclinations. Using these net Burgers vectors and their associated densities, ad-ditional forces due to stress field were calculated via the Peach-Koehler equation. Qualitativecomparisons of 5 parameter grain boundary character distribution will be carried out in orderto analyze the differences in texture evolution during grain growth.
